27 | ;; This package provides functions which read a URL (Uniform Resource | |
28 | ;; Locator) from the minibuffer, defaulting to the URL around point, | |
29 | ;; and ask a World-Wide Web browser to load it. It can also load the | |
30 | ;; URL associated with the current buffer. Different browsers use | |
31 | ;; different methods of remote control so there is one function for | |
32 | ;; each supported browser. If the chosen browser is not running, it | |
3abc9fa1 DL |
33 | ;; is started. Currently there is support for the following browsers, |
34 | ;; some of them probably now obsolete: | |

54 | ;; [A version of the Netscape browser is now free software | |
55 | ;; <URL:http://www.mozilla.org/>, albeit not GPLed, so it is | |
56 | ;; reasonable to have that as the default.] | |
57 | ||
58 | ;; Note that versions of Netscape before 1.1b1 did not have remote | |
59 | ;; control. <URL:http://www.netscape.com/newsref/std/x-remote.html>. | |
60 | ||
61 | ;; Browsers can cache Web pages so it may be necessary to tell them to | |
62 | ;; reload the current page if it has changed (e.g. if you have edited | |
63 | ;; it). There is currently no perfect automatic solution to this. | |
64 | ||
65 | ;; Netscape allows you to specify the id of the window you want to | |
66 | ;; control but which window DO you want to control and how do you | |
67 | ;; discover its id? | |

107 | ;; Help! | |
108 | ||
109 | ;; Can you write and test some code for the Macintrash and Windoze | |
110 | ;; Netscape remote control APIs? (See the URL above). | |
111 | ||
112 | ;; Do any other browsers have remote control? | |
113 | ||
114 | ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; | |
115 | ;; Usage | |
116 | ||
117 | ;; To display the URL at or before point: | |
118 | ;; M-x browse-url-at-point RET | |
119 | ;; or, similarly but with the opportunity to edit the URL extracted from | |
120 | ;; the buffer, use: | |
121 | ;; M-x browse-url | |
122 | ||
123 | ;; To display a URL by shift-clicking on it, put this in your ~/.emacs | |
124 | ;; file: | |
125 | ;; (global-set-key [S-mouse-2] 'browse-url-at-mouse) | |
126 | ;; (Note that using Shift-mouse-1 is not desirable because | |
127 | ;; that event has a standard meaning in Emacs.) | |
128 | ||
129 | ;; To display the current buffer in a web browser: | |
130 | ;; M-x browse-url-of-buffer RET | |
131 | ||
132 | ;; To display the current region in a web browser: | |
133 | ;; M-x browse-url-of-region RET | |
134 | ||
135 | ;; In Dired, to display the file named on the current line: | |
136 | ;; M-x browse-url-of-dired-file RET | |
137 | ||
138 | ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; | |
139 | ;; Customisation (~/.emacs) | |
140 | ||
141 | ;; To see what variables are available for customization, type | |
142 | ;; `M-x set-variable browse-url TAB'. Better, use | |
143 | ;; `M-x customize-group browse-url'. | |
144 | ||
145 | ;; Bind the browse-url commands to keys with the `C-c C-z' prefix | |
146 | ;; (as used by html-helper-mode): | |
147 | ;; (global-set-key "\C-c\C-z." 'browse-url-at-point) | |
148 | ;; (global-set-key "\C-c\C-zb" 'browse-url-of-buffer) | |
149 | ;; (global-set-key "\C-c\C-zr" 'browse-url-of-region) | |
150 | ;; (global-set-key "\C-c\C-zu" 'browse-url) | |
151 | ;; (global-set-key "\C-c\C-zv" 'browse-url-of-file) | |
152 | ;; (add-hook 'dired-mode-hook | |
153 | ;; (lambda () | |
154 | ;; (local-set-key "\C-c\C-zf" 'browse-url-of-dired-file))) | |

183 | ;; t) ; => file written by hook | |
184 | ;; t))) ; append to l-w-f-hooks | |

187 | ;; file: | |
188 | ;; | |
189 | ;; (add-hook 'browse-url-of-file-hook 'browse-url-netscape-reload) | |
